Don't switch on the fly, that's just stupid. You'll need a whole system overhaul.
Sway bar bushings
Your problem is generally the strut mounts. If it's making a clunk sound... Get new struts and mounts, and possibly sway bar links. I have a 2001 Volvo s40 t4 and have had to change these before. Hope this helps
cv joints
New CV joints will fix the grinding noise
the noise could be coming from either a bad wheel bearing or something wrong in front axle.
I think i can help; where are you from?
It is the fan blower for the engine cooling system (Radiator)
low on oil, crankshaft and bearings bad
Could be a bad wheel bearing front or rear.
The minimum thickness for the rotors of a 2001 Mazda B3000 is 0.5 inches for the rear and 0.97 inches for the front. Falling below this threshold can result in poor braking performance.
Diod you check front brake pads
if it is when u are driving it might be thr door or the speaker or if it is closer to the front of the car possibly the transmission
